Angles ∠ACD and ∠CAB are congruent because they are alternate angles. Then the area of the triangle AOB will be 22.53 square cm.
<h3>What is the
area of the right-angle triangle?</h3>
The area of the right-angle triangle is given as
A = 1/2 x B x H
Where B is the base and H is the height of the right triangle.
We know that angles ∠ACD and ∠CAB are congruent because they are alternate angles.
α₁ = 40°
AO = OC = 7.8 cm
Then the area of the triangle will be
Area = 1/2 x 7.8 x 7.8 x tan40°
Area = 22.53 square cm

Answer: 150 miles
Step-by-step explanation:
m = mile
40 + 0.25m = 25 + 0.35m
0.25 * 150 = 37.5
37.5 + 40 = 77.5
0.35 * 150 = 52.5
52.5 + 25 = 77.5
77.5 = 77.5

Answer:
No.
Step-by-step explanation:
Of course not. Place a hardback book standing up on your desktop and open the two hard covers to some arbitrary angle. The planes of the covers are each perpendicular to the desk top, but not parallel to each other (or necessarily perpendicular to each other).
